Dr. Petr Bednarik


The revolutionary deuterium-MRI imaging technique developed at the High Field MR Center, Medical University of Vienna, enables monitoring of glucose metabolism and neurotransmitter dynamics in the brain. Traditional methods for tracking glucose dynamics necessitated the use of intravenous radioactive tracers, limiting accessibility and safety for patients. However, this innovative method, utilizing orally administered deuterium-labeled glucose, promises to revolutionize neuroimaging by providing a non-invasive and non-radioactive alternative. By precisely monitoring glucose and neurotransmitter metabolism, crucial for understanding brain function and implicated in conditions such as Alzheimer's disease and brain tumors, this advancement holds immense potential for both research and clinical applications. Dr. Bednarik’s groundbreaking development represents a significant step forward in neuroscience, offering safer and more effective diagnostic avenues for understanding brain metabolism and function.
